This invention relates to perforating machines and more particularly to a device for automatically perforating a record card in predeterm ined columns.

Statistical machines and the like, particularly punching machines have been combined with other machines, as for instance, typewriters, calculating machines, cash registers, etc. In the present instance I have 19 shown a punching machine combined with a typewriting machine. The purpose of such a combination is to repeat the results effected by manual or other operation on one machine in the other machine. Thus, certain data may be typed on a record sheet and simultaneously perforated on a'record card, the in formation perforated on the record card corresponding to data being typed on the record sheet.

In commercial practice it is oftendesired to print certain information on a record sheet and not perforate this information on a record card. As an example, a clients address, such as Blank Street, is typed on the record sheet and if means were not provided for suppressing the operation of the punching mechanism the figures .50 would be perforated' in the record card. This number on the card would have no significance.

The principal object of the present invention is to provide a practical and effective mechanism for so suppressing such data with minimum effort on the part of the machine operator.

5 Another object of my invention is to provide a printing and perforating machine wherein data may be perforated in connection with predetermined columns of the printed sheet during the printing operation and perforating is automatically suppressed in connection with other columns.

Another object of the invention is to provide for selectively predetermining suppression of perforating in any desired position in a. machine of the above type.

Various other objects and advantages of my invention will be obvious from the following particular description of one form of mechanism embodying the invention or from as an inspection of the accompanying drawing;

form of mechanism embodying the inven tion in which Fig. 1 is a detail view of a punch showing oneof the selector magnets and associated parts including one of the punches, the parts being shown in section.

Fig. 2 is a side sectional view of a typewritter machine used in connection with my invenion.

Fig. 3 is a wiring diagram showing the manner in which the perforating of a record card is controlled.

For an understanding ofthe invention certain parts of the perforating machine used in connection with my invention and its op.- eration will now be described.

Referring to Fig. 1 each selector magnet 10 is provided wit an armature 11 pivoted at 12. The armature 11- is provided with a forwardly extending lever 13 overlying vertically movable plungers 14 slidably mounted in. the machine. Each plunger has one leg of a. bell crank 15 slidably connected thereto, the opposite ends of said bell cranks being connected to separate controlling slides which will be hereinafter called intcrposers and are poser 16 so that the notch 17 is carried out of. the path of the punch actuator 1.8 which, if then operated, will be brought directly into contact with the upper surface of the interposer and depress the same. Each of the in terposers has its forward end arranged over a noted, passes between the stripper plate 21 and a die 25 fitted in the table of the punch.

This die is provided with a plurality of open-I ings 26 one for each punch which receive and pass the discs punched out of the card.

Each inter-poser is provided with a notch 27 on its under surface which are aligned when the interposers are in retracted position. These interposer notches are arranged to receive an interposer stop and a common switch operating bar 28.' This switch bar is normally held in retracted position by a spring which is connected to the insulated finger 29 of a movable switch contact element 30 by a link 31. This link has its free forward end provided with a shoulder 32 which is engaged by the forward side of the bar 28 e and the link is held down in a guiding notch of the bar by a spring 33. The free end of the'link 31 is also provided with a hook 34 which is engaged over a laterally projecting finger 35. When the contacts 29 are closed a circuit is established to the punch actuating magnet 36. Connected to the armature 37 of the punch actuating magnet 36 is an arm 38 fixed on a shaft 39 on which is also fixed the actuating bar 18. When themagnet 36 is energizedits armature 37 will actuate arm 38 rocking shaft 39 causing counter clockwise operation of bar 28 depressing the selected interposer 16 which in turn pushes the corresponding punch 19 through the card. Each time a punch is actuated a lever 40 is rocked downwardly.

This lever controls the feeding of the card column by column through well known escaping mechanism. The punch mechanism thus briefly described forms, per se, no part of the present invention and is described in detail in the copending application of J. T. Sch jaaif, Serial No. 731,980, filed August 14, 192

Referring now to Fig. 2 a typewriter with provisions for controlling a perforating maillustrated. As the general construction of a typewriter is well known, it will be unnecessar for me to go into detail but it is to be un erstood that instead of utilizing the standard numeral key board, I may substitute therefor, a numeral key board ranging from 1 to 12, or in other words, a key for each of the usual punching positions on a record card. One of the numeral keys 41 is shown and.

through well known linkage is operativelyconnected to a printing element 42 carrying type corresponding to the key thereon. Pivotally'mounted directly beneath the numeral key 41 is an actuating member 43 which when rockedin a downward direction by the numeral key 41 closes a set of contacts 44. It is .to be noted that the actuating member 43 has fixed thereto at 45 an insulated block for closing the contacts 44 and that each numeral key 41 has an actuating member 43 and an associated set of contacts 44 cooperating therewith. Fixed to the frame of the typewriting machine at 46 is a bracket 47 having insulated therefrom at 48 a sliding contact 49. This contact engages the upper surface of a metallic rail or contact 52 fixed to the carriage 50 of the typewriter at 51, .the rail being insulated from the carriage by a strip of insulation 51*. In the general operation of the machine, simultaneously with the printing of a numeral on the record sheet, the contacts corresponding to the numeral key depressed will be closed in the manner previously described, setting up a circuit to the selecting magnet 10 (Fig. 1) of the punch-- ing device, and through the metallic rail 52 and sliding contact 49 the punching magnet 36 will be energized causing a perforation to be made in the card. The circuit is as follows: from the positive side of the source, through contacts 44, now closed, magnet 10, wire 54, metallic rail 52, individually removable metallic contact clips 57 having a dovetailed connection to bar 52. sliding contact 49, wire 55, resistance 56 and back to the negative side of the line.

As previously stated it is often desired to print certain information on a record sheet and not perforate this information on the record card. In ordertodo this the operator will insert an insulated clip 53 upon the metallic rail 52 in a position corresponding to the carriage position in which perforating is not desired. The operation of the machine is the same as previously described,

but the circuit to the punching magnet 36 is broken due to the sliding contact passing over the top of the insulated clip 53. In other words for each typewriter carriage position for which the record card is not to be perforated, an insulated clip 53 is inserted on the metallic rail 52.

While I have shown and described and chine in accordance with invention i pointed out the fundamental novel features of the invention as applied to a single modification it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention. I intend to be limited therefore only as indicated by the scope of the following claims.

What is claimed is:

.1. In combination, a typewriter with a movable carriage for selecting different printing positions, an electrically operated punch with selector circuits therefor controlled by the ty ewriter and a circuit controller common to'said circuits having a stationary contact member and a conductor member movable with said carriage.

2. In combination, a typewriter with a movable carriage for selecting difi'erent printing positions, an electrically operated punch with selector circuits controlled by the typewriter and a circuit controller common to said circuits having a stationary contact member and a coacting contact member movable with said carriage and provided with insulating portions for suppressing operation of said control circuits in predetermined carriage positions.

3.
